Introduction This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it extends [RFC2819] with managed objects used for real-time application QOS monitoring. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 2. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 3. RAQMON Framework As outlined in [RAQMON-FRAMEWORK], the RAQMON framework is based on three entities: RMON MIB WG Expires May 2004 [Page 2] INTERNET DRAFT RAQMON MIB November 2003 - RAQMON Data Source (RDS) - RAQMON Report Collector (RRC) - RAQMON MIB Structure The RAQMON MIB runs between RRCs and a RAQMON Application ('RAQMON manager') 4. Structure of the RAQMON MIB The RAQMON MIB module is composed of three MIB groups: The raqmonSession MIB group incorporates the following tables: - raqmonParticpantTable contains information about participants in open and closed (terminated) sessions - raqmonQosTable contains historical information about QoS during sessions - raqmonParticpantAddrTable maps particpant addresses into the index of the raqmonParticpantTable The raqmonException MIB group includes a table of filters that trigger notifications for sessions with poor QoS. The raqmonConfig MIB group includes object that define the configuration of the RAQMON collector. This MIB module is implemented by the RAQMON collectors. A separate MIB module is defined by [RAQMON-PDU] for mapping of the RAQMON PDUs in an SNMP transport. The MIB module defined in [RAQMON- PDU] is implemented by the RAQMON Data Sources (RDS). 5.

Security Considerations There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. Setting the following object to incorrect values can result in collectors either flooding the management applications with unnecessary notifications, or not sending notifications when the QoS in the network may be degraded. raqmonSessionExceptionJitterThreshold raqmonSessionExceptionRttThreshold raqmonSessionExceptionLostPacketsThreshold Setting the raqmonConfigPort object to incorrect values can result in the collector not being able to receive RAQMON PDUs from the data sources. Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. These are: raqmonParticipantTable raqmonQoSTable raqmonParticpantAddrTable Unauthorized exposure of these objects may lead to disclosure of the addresses of the participants in applications, or information about the traffic patents of the applications, which may be considered sensitive in certain environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt their values when sending them over the network via SNMP. SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). RMON MIB WG Expires May 2004 [Page 27] INTERNET DRAFT RAQMON MIB November 2003 Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them. 10.
